Java8 new Features-stream

The collection interface in JAVA8 is extended to provide two ways to get the stream:

Default Stream<e> Stream (): Returns a sequential stream

Default Stream<e> parallelstream (): Returns a parallel stream

1 Create

1. Collection provides two methods for stream () and Parallelstream ()

New Arraylist<>(); Stream// get a sequential stream // get a parallel stream

2. Get an array stream through stream () in Arrays

New Integer[10]; Stream<Integer> stream1 = Arrays.stream (nums);

3 static method by Stream class of ()

    stream<integer> stream2 = Stream.of (1,2,3,4,5,6);

4 Creating an infinite stream

// Iteration        stream<integer> stream3 = stream.iterate (0, (x), X + 2). Limit (n);        Stream3.foreach (System.out::p rintln);

5

    // Build        stream<double> stream4 = stream.generate (math::random). Limit (2);        Stream4.foreach (System.out::p rintln);
